Specification of Letters Patent.

Patented July 28, 1908.

Application filed November 4, 1907. Serial No. 400.562.

To all whom it mciy concern." I

Be it known that 1, ANDREW SHEARER, a citizen of the United States, residing at Frankfort, in the county of Marshall and State of Kansas, have invented'certainnew and useful Improvements in ListerPlows, of which the following is a specification.

This invention relates to lister plows and my object is to produce a machine having a whee -suppcrt at one side to run in the furrow, a wheel-support at the opposite side to run on unbroken ground, a plow to' produce a furrow parallel tothat occupied by the first-named wheel-support, and a wheel-sup' port to travel in the furrow being made by the plow, and means whereby the operation of a single lever shall result in reversing the positions of the side-wheel supports without,-

affecting the depth or level of theplow.

A further object is to produce means for vertically adjusting and supporting the plow at varying heights without changing itsjangle and therefore its suctional relation to the ground.

Another object is to produce a machine hich cannot tip over and is easily guided byproviding a low-down frame, open at' its 'centcr, with small wheels two rows apart,

and axles therefor at opposite sides of said openingto permit the plow and its beam to be raised into said-opening between the axles.

Another object is to produce a plow having .a pair of axles each equipped with a pair-of wheels capable of beingdisposed at varying distances apart to correspond to the Width of the furrow turned by the plow.

With these general objects in view and othersas hereinafter ap ear; the invention consists in certain novei and peculiar fea tu'res of construction and organization as hereinafter (.lescribed-and claimed and in ordo." that it may be fully understood reference is to'be had to the accompanying drawings,

Figure 1. is a top plan View, with the seat on iitt-ed, of a lister plow embodying my in-' vention. Fig. 2, is a frontview of, the machine. Fig. 3,.is a section on. line III- II of Fig. 1. Fig. 4, is a detail perspective view of theinner ends of-the crank axles and.

crank shaft above the same and the links piv'otallv connecting-said crank shaft lwith the sand axles. l

In the drawings aframe open at its center is preferably constructed of a metal bar bent to form the-transverse rear portion 1, side portions 2 diverging forwardly from portion 1, parallel portions 3 extending forward from the diverging portions 2, forwardly converging portions 4 projecting from the front ends of portions 3 and parallel portions 5 projecting from the front ends of portions 4, the frame'being completed-preferably by uniting" 10 is a bracket secured rigidly as shown or in any other suitable manner to the rear end of the body of the rigid frame described and provided with a vertical sleeve 11 to provide a journal for the'upper portion of a caster rod 12, the sleeve being slotted to receive the collar 13 mounted upon the rod to prevent it said caster is secured rlgldly as regards swivel movement to the frame, the means for locking and unlocking the caster rod to the frame being unimportant as .regards this application. 7

16 indicates thc seat arranged vertically over the caster and secured to the upper end of-a spring support 17 attached at its lower end in any suitable manner, to the rear end of the frame. I}

A pair of axles consist of the transversely extending alined' portions 18, the transversely extending portions 19, and the crank portions 20 connectingthe outer ends of portions 18with portions 19 and extending by preference at approximately. an angle of 'orty-five degrees to each other. tions 18 extend through and are jot: 7310 1 in bearing brackets 21 secured to andhdepcnd ing-frorn the wings of the frame and at their inner ends are journaled in the lower ends of an arch 22 connecting the rear ends of pertions 50f the body portion of the frame, the

archb'eing made rigid with the frame in any suitable manner. Wheels 23 are journaled on portions 19 of the crank axles described, between collars 24 secured on said portions of the crank axles by set screws 25 or in any equivalent manner, one or more spacing sleeves 26 being also mounted on each portion 19 between its respective wheels 23. 27 and 28indicat'e short cranks secured on said crank axles near their inner ends and projecting from the same with res ect to each other at the same anglethatcran s 2O bear to each other it being noticed, however, that crank 27 of the right hand crank axle projects from the opposite side of said axle from its companion crank 20 and that the same is true of,

the cranks of-the lefthand axle.

29 and 30 are links pivoted at any desired point near their lower ends, to cranks 27 and 29 respectively. The link 29 is pivotedat 2a Lts upper end to the forwardly projecting 1 crank 32 of a short shaft 31, the upper end of link 30 being pivoted to the oppositely projecting crank 33 at the opposite end of shaft 31. Crank shaft 31 is arranged parallel 30 With the wheel carrying crank axles described and is disposed about vertically over the pivotal points of connection of cranks 2] and 28 with links 29 and 30 when the left hand wheels 23 are in a furrow and the right 35 hand wheels are upon unbroken ground, the said crank shaft 31 being journaled in parts cast with or rigidly secured to the upper end of the arch 22. 34 is a lever secured rigidly to the shaft 31 its left hand end by preference, and provided with a catch mechanism 35, for engagement with the sector 36 also cast with or rigidly secured to the arch, 37 is'a trans verse bail arranged about midway the length of the frame amljournaled at its ends in brackets 38 and 39 secured rigidly to and projecting upward froin portions 3 of the frame, the right hand bracket by preference bein formed with the toothed sector ll); 41 is a ever secured to the right hand end of bail 37 and 42 a catch mechanism carried thereby for'cngagement with the sector 40. The crank portion 43 of the bail depends through the opening of the frame and is journaled inbearing brackets 44 secured to opposite sides of and depending from the longitudinally extending beam 45 of a plow 46. 47indicates a bracket secured to the front 7 portionof the beam forward of the whccl- 0 carrying crank shafts and provided with depending bifurcated and slotted arms 48l'fitting over said beam, bolts 49 extending through said arms and beam for the purpose of securing, bracket 47 at the desired height 35 above thebe'amf the bracket being longitudinally slotted to provide a longitudinal slot 50 for the beam, in which slidingly fits the crank portion 52 of a \l-shapcd hail 51, journaled at its opposite ends in brackets 53 secured to and depending from portions 5 of 7 the frame.

54; indicates a short crank a rm secured to and projecting upward from the right hand end by preference, of bail 5i, and 55 is a rod pivotally linking the said crank arm 54 with. lever 41.

56 is a' drill of any suitable type carried by and rearward of the plow in any suitable manner, reference to the detail constriu'tion of the drill being omitted as forming no dca pendent part of the preseiitinvcntion.

Before proceeding with the description of the method of operating the machine it is dcsired to call attention. to the fact that the machine possesses the greatest stability by 3:, reason of the fact that it is much lower than ordinary three wheeled plows, the arches being provided to accommodate the beam when the plow is elevated above the ground. Said. arches furthermore coi'ipcralc with any no suitable bracing, not shown, in making the comparativcly wide and light frame thoroughly still and rigid, it being also noted in this connection that the body of the frame is of such character as to permit the plow to day vertically through it when raised and lowered. .It is also desired to call attention to the fact that the employment of comparatively small carrying wheels permits of the use of the low frame and that withlow wheels the machine can be guided more easily in the path desired because the pair of wheels which will travel in the furrow cannot so easily roll up out of such furrow as large wheels.

In the ordinary operation of the nnrchine the )arts will be arranged as shown, the cran of the lifting bail being vertically pend- 'ent and the crank of the left-hand carrying axle disposed downward and slightly rearward and the crank of the rightehand wheclcarrying axle projecting rearv'vard, this arrangement disposing both sets of carrying wheels rearward. of the axis of their axles and almost directly opposite each other, it being understood that the furrow occupied by the depressed or left-hand wheels is that which was made by the plow in the preceding trip of the machine across the field, it being further noted that the caster travels in the fur row being turned at the time by the plow and that as hereinbcfore explained, it is held rigid when thc plow is depressed and will be free to turn as a caster when the plow is elevated or in inoperative position. it will also be noted that when the plow is depressed to operative position by swinging the lifting leve 4H forward, the link rod 55 swings crank arm 54; forwardv so as to cause the bail 52 to slide forward on and press the front cud of thebeam downward at the same time for the 1.;(1

. eretofore lister se4fso2 purpose of preserving the proper position of the plow, to maintain its required suction on connected to the beam substantially like the lifting bail of-thisapplicatiombut such E0011- q of unequal depth.

.single bail i'semployed to support the plow structions are objectionable in that the beam is maintained rigidly in a certain relation with the ground and consequently the plow will only work well at a particular depth, so

that if the plow'should go deeper, the wheel behind it would of course drop also and thus lower the rear end of the beam and change the pitch ofthe plow so that thelatter will tend to move upward and produce a furmw On the other hand if a and it is attempted by means of the lever to force the plow deeper into the ground, the

point of theplow will become higher than the heel and if the lever is moved far enough the weight of the frame and of the driver will be carried by the plow.'and impose a killing weight on the horses. By having the bracket 47 vertically adjustable so as to vary the height of slot 50 the angle of the plow can be changedso as to give it a different angle or suction with relation toThe ground, this adjustment being desirable to accommodate the condition of the ground or the degree of sharpness of the plow. When the ground is very rough the bracket 47 may beentirely omitted soas to allow the beam to play downward freely in the event that the wheels run over' clods or other 'obstructions in their paths.

In the practical operation, the depressed wheels 23 run in the lastmade' furrow as shown in Fig.- 2 and the caster runs in the furrow being made by the plow and coeperates with the depressed wheels in compelling the plow to parallel the furrow occupied by the depressed wheels, it being noticed that by disposing both sets of wheels 23 with their axes rearward of the axes of portions 18 of their carrying axles, the machine tends to travel in a more strai ht and direct course than if the distance etween said wheels, measured longitudinally of the machine was greater. After the furrow has been completed, the operator by pulling rearward on lever 41 raises the plow out of the ground and incidentally the drill, and before turning the machine, he operates lever 34 so as to simultaneously raise the left hand and lower the right hand wheels '23 until their axes are longitudinally alined, thus bringing the said wheels to the same level to permit the machine to beturned more easily. 'Ifthe machine is to be driven across the field in the opposite direction to that which it followed in making the last furrow, he continues the said movement of lever 34 after the. turn is made for the purposepf raising the lefthand and loweri V plane of the ottom of the'furrows so'that the wheels to the plane of the unbroken ground he 'right hand wheels to the machine on the return trip shall produce a new furrow with the originally elevated wheels running in the last-named furrow and the ori inally depressed wheels running upon the un roken ground, it being apparent that the reversal of the positions of the wheels occurs without affecting the depth of the plow or varying its angle or level with respect to 'the ground. v

From the above description it will be apparent that I have produced a lister plow possessing the features of advantage enumerated as desirable in the statement of the object of the-invention and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described as obvious modifica- I claim as new and desire to secure by Letters Patent, is I 1.
